'LocoMorIv DRIVING BOX.

Application filed April 18, 1924. Serial No. 706,970.

To all whom it may concern.

Be, it known that HERBERT T. LINDFORS and WILLIAM B. LoLLIs, citizens of the United States, residing at Columbia, in the county of Richland and State of South Carolina, have invented new and useful Improvements in -Locomotive Driving Boxes, of which the following is a specifi- This invention relates to improvements in driving boxes for vehicle wheels, and particularly to adjustable wedging means for taking up excessive lateral play between the driving box and the hub of a locomotive I semi-circular bushing'15 which engages the wheel. I

When the excess lateral motion between a locomotive wheel and its driving box exceeds a predetermined. amount, Government regulations require that it be immediately reduced to within certain limits. Hereto fore it has been necessary in order to correct for this excess lateralplay, to remove the wheel and axle from the locomotive,

which entails considerable expense and delay.

A primary object of the present invention consists in the provision of means positioned between the ends of the driving box and the supporting frame, whereby any excess lateral movement can be quickly corrected without the necessity of dismantling any of the parts, by simply adjusting the wedges, which willefi'ectively maintain the driving box substantially square to the hub of the wheel at all times.

A further object of the invention relates to the provision of an adjustable wedge positioned between one side of the supportmg frame and the driving box,which may be readily adjusted when the parts become loose, so as to maintain the frame and the axle in proper relation.

Referring to the drawings,'wherein is set forth a preferred embodiment of the invention: f a

' Figure '1 is a sectional viewtake'n substantlally along the line 1-1of Figure3,

Figure 2 is a vertical sectional view'taken substantially along the line 2-2 of Figure 1,

Figure 3 is a sectional view taken subor the like,

24,as shown in Figure 1.

Figure 5 is a sectional view taken substacptlally alongthe line 55 of Figure 4, Figure 6 is a sectional view taken substantially along the line 6-6 of Figure 4.

Referring to thedrawings, wherein like numeralsindicate like parts in the several views, 10 denotes the frame of a locomotive, having an opening 11 therein, in which is supported the driving box 12. The axle 13 journalled in the driving box 12 has secured thereto the locomotive wheel 14 in any suitable manner.

The driving box 12 is'provided' with a axle 13, and is also formed with the dethe lugs 18 and 19, respectively arranged to register with the complementary lugs 20 and 21 on the saddle plate 22, and detachably connected thereto, by

In order that excessive lateral motion between the driving box 12 and the face of the hub 25 of the locomotive wheel may be readily taken up, without the necessity of dismantling any of the parts, the driving box 12 is preferably provided with the 01it-' ward projecting, radial, end'fianges 26 and 27, as shown in Figure 3. Interposed between the pedestals 16 and 17' of the frame 10 and the adjacent sides ofthe driving the bolts 23 and box, there are arranged a pair of slippers 28 and 29, having end flanges 30 and 31, which extend parallel with and engage the flanges 26 and 27 of the driving box.

The opposed inner walls of each of the flanges 30 and 31 are preferably recessed and tapered downwardly, as at 32'and' 33, so as to receive and'ifrictionally engage the complementary faces of wedges 34, 35, 36 and 37, positioned between the frame 10 and the end flanges 26 and27, for co-acting with the slippers 1n maintaining the driving box in'prop'er position relative to the wheel 14. By reason of the recesses 32 and 33 formed in the slippers, the wedges Will be prevented from moving laterally when the parts are set up.

The wedges are each'. provided with threaded shanks 37 which extend through suitable openings formed in braces 38, preferably secured to the lower portion of the frame 12. The wedges .are maintained in fixed adjusted position relative to the slippers by means of the retaining nuts 39 and 40 threaded to each of the shanks 37. v,

In order to reduce to a minimum the amount of lost motion between the driving box and the frame 10, a wedge 41 is preferably positioned between the fpedestal 17' of the box and the adjacent sur per, as shown in Figure 3. The wedge 41 has connected to its lower end a threaded bolt 42 which extends through the frame 10 and is maintained in position thereon by the retaining nut 43, as shown in Figure 2.

To overcome excessive lateral play between the driving box 12 and the locomotive wheel 14, it will be merely necessary to loosen the inside wedges 34 and 37 and tighten the outside wedges 35 and 36 by suit ably adjusting the nuts 39 and 40 on the shanks .37. As these wedges are independently adjustable, they may be separately regulated to secure any desired adjustment. Furthermore, should it. be required to take up lost. motion between the side of the driving box and the frame 10, this can be done by ti htening or loosening the wedge 41, as ma e required.

y reason :of the present construction, it will be apparent that any lost motion or excess lateral play between the frame 10, the driving box 12, and the wheel 14 can be readily corrected by making the necessary adjustment to the severalwedges, as before set forth, without the necessity of dismantling the parts.

In the modified form of the invention illustrated in Figures 4, 5 and 6, the rear wedges are shown connected at the top of the frame, while the forward wedges are attachedto the bottom thereof in contradistinction to having all the wedges secured to the bottom of the frame, as shown in 1he.

form previously set forth. Otherwise the construction and operation of the parts are identically the same as those previously described.

Referring particularly to the modified form of the invention, the driving box 44 is movably maintained in the. supporting frame 45 by means of the end flanges 46 and 47, between which and the adjacent ends of the frame are interposed the slippers 48 and 49. These slippers are provided with the flanges 50 and 51 formed on their inner surfaces'with downwardly tapered recesses 52 and 53 which receive the complementary tapered surfaces of the wedges 54, 55, 56 and 57, respectively.

The threaded shanks 58 of the inside wedges 54 and 55 are preferably connected to the top of the supportin frame 45 by the bracket 59, to which the s anks 58 are adjustably secured by the nuts and 61, as shown in Figure 5. Similarly, the outside wedges 56 and 57 have their shanks 58 conace of the slip- 7 nected to the braces 62 on the underside of the frame 45 by means of the nuts 63 and 64. Obviously, this particular arrangement could be reversed without in any way departing from the sec e of the invention.

A wedge 65 prefera lyinterposed-between the slipper 49 and the adjacent wall of the frame 45 .is provided to compensate for any excessive lost motion between the driving box and the frame member. A threaded bolt 66 connected to the lower end of the wedge 65 projects through a suitable opening formed in the frame 45 for permitting the wedge to be adjusted relative to the supporting frame, and is maintained in predetermined position by the nut 67.

The axle 68 having the wheel 69 connected thereto,'is mounted within the driving box 44 and is detachably connected thereto by means of the saddle plate 70 which is attached to the frame by the retaining bolts 71 and nuts 72.

When excessive lateral motion occurs be-. tween the driving box 44 and the locomotive wheel 69, it can be readily corrected by selectively adjusting the several wedges in the manner as may be desired. Furthermore, should it be necessary to take u lost motion between the driving box an the frarie, the wedge 65 can readily'be tightene It is to be understood that the forms of the invention herewithshown and described are merely illustrativeand in no sense restrictive, and that such changes as fall within the purview of one skilled in the art may be made without departing, from the spirit of the invention and the scope of theappended claims.
